Abstract: According to an aspect, a display system includes: a wearable part; a first display device having a first display region; a second display device having a second display region; and a drive circuit. The first display region and the second display region are provided with sub-pixels arrayed along a first direction and a second direction. The sub-pixels include first sub-pixels, second sub-pixels, and third sub-pixels. The first sub-pixels are continuously arrayed in a third direction inclined with respect to the first and second directions, the second sub-pixels are continuously arrayed in the third direction, and the third sub-pixels are continuously arrayed in the third direction. A first angle between a fifth direction and the third direction is smaller than a second angle between the second direction and the third direction. The fifth direction is orthogonal to a fourth direction in which the first and second display regions are arranged.
